More specifically the invention relates to con' structional units adapted to be employed as a weatherproof covering that closely simulates a brick Wall. y

Heretofore, for this purpose it has been proated units, each unit conrip having narrow spaced terial adhesively secured are expensive to manuper spacing and cementing o the base is a time consk. Moreover, when strips of this nature are laid on th'e side Walls of a building, the structure is subject, under the action of the weather, to the tendency towards delamination.

Accordingly,

strips of roofing ma thereto. These strips facture because the pro of the narrow strips t closely simulate a brick, stone or other like Wall, and are not subject to delamination when exposed to the weather.

Another object of my invention resides in the novel manner ofl procedure for manufacturing the constructional units.

In the accompanying drawing:

Figure 5 is a transverse section of one of the units taken along -line 5 5 of Figure v1;

Figure 6 is a similar viewtaken along line 6 6 of Figure 2; and

.Figure '7 is a similar of Figure 2. p In accordance with my invention, the constructional units may consist of unitary structures of moulded or compressed pulp such' as wood pulp, can pulp or other suitable material or a thermoplastic brous composition board made on a 'paper machine from suitable mixtures of fibre tional view taken on line 4 4 view taken along line 1 -'l 1931; serian No. stesse (ci, zc-s) and aqueous dispersions of a waterproof thermoplastic substance.

An embodiment of my invention consists in the use of a water-resistant material having thermoplastic properties, such as that made on a, paper making machine from a suitable mixture lof `V`iibrous material and aqueous dispersion of asphalt. Material of this character in which the Waterproof thermoplastic ingredient is incorporated with the bre before formation into sheets or boards 1s readily susceptible to shaping as by moulding or embossing operations. According to the constructional unit or strip is of general rectangrular shape with upper and 42 respectively and side edges43 and 44. The strip is provided with raised substantially rectangular areas bordered along their upper edges by a' horizontal depression 46; the upper extremity of which is space distance equal to the desired horizontal lap and the lower extremity of which is spaced front the and lower edges 4| In order that the finished strips may be laid in overlapping courses with the bottom face of each y adjacent the top face of the pressions 41, that the verti d from the edge 4| a between the vertical center lines of the depres- The depression l2 is of the same or the depression 48, and is located a predetermined distance from one of the lateral ends of the strip to' provide the proper amount of lap between adjacent s gies.

According to my invention the recta guiar areas of the thermoplastic unitary strips are provided with a'coatlngy of weatherproof material in which is partially embedded granules of a color resembling that of the usual varieties of brick and' contrasting with that of the recesses or depressions of said strip, to present brick simulations standing out in relief beyond the mortar jo t simulations afforded by the recesses or dep essions.

Constructional units of this character may be "produced in accordance with my invention byfollowing the steps to be presently outlined.

Whatever the composition of the base, it lmay be coated over its entire area, or on the portions to be exposed, or only on the exposed face of the raised or relief areas, with a suitable weatherproof material such as a high melt point asphalt or similar bitumen. be accomplished in any suitable manner, such as by dipping the strips in a bath of the coating .material or by spraying, doctoring or otherwise applying'the coating material to the desired portions or areas of the strip.

Thereafterand while the coating on the face to be exposed is still tacky, the surfacing material is applied thereto in such only the rectangular relief areas. This may be accomplished, for example, by placing the' coated faces of the strips in contact with a bed of granules, such as comminuted slate, slag or the like, of suitable brick color. Where coating material is, applied to the grooves or depressions as well as to the relief or raised areas, care should be exercised in the surfacing operation to preclude the brick or other light colored granules from adhering tothe coating in the grooves or depressions and thus impair the mortar effect intended to be 'provided by the depressions. To this end, the depth of the bed and the size of the granules 'in this operation should preferably be so related to the depth sions in the strip that when the coated face of the strip is brought into contact with the granules, the latter will be picked up by and adhere only to the areas in relief, leaving the depressions or grooves unsurfaced and of a dark or black color. If desired, howevenwhere the coating material has been applied also to the grooves or depressions, the latter may be surfaced with black or other colored granules contrasting with that of the granules on the rectangular relier areas and of a size preferably liner than said last mentioned granules. This surfacing may readily be 4said base pression extending This coating operation may a way as to cover.

of the grooves or depres-` partially syrfaced -bed vof ilne ,black be picked up by the grooves or accomplished by pressing the face 'into a. sufilciently /deep granules to permit the latter to the adhesive or tacky coating in depressions. y
